JPS6029094Y2 - Operation and display device in record player - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation and display device for a record player.

Although there are various types of record players, conventional record players generally have a structure in which a pickup such as a tone arm is placed on the side of a turntable.

In a record player having such a structure, the turntable and the pickup occupy a large area in a plane including the turntable, so it is not easy to downsize the player body.

For this reason, as shown in FIG. 1, the player body 1 is downsized to a size slightly larger than the turntable 2, so-called record jacket size, and a dust cover is used as a lid member that can be opened and closed with respect to the player body 1. An ultra-compact record player having a configuration in which a pickup 4 is attached to a record player 3 has been developed.

Such small-sized players have the disadvantage that they lack operability because the space for the operation and display device is limited, which limits the size and shape of the operation switches and display elements.

An object of the present invention is to provide an operation and display device for a record player that eliminates the above-mentioned drawbacks.

The operation and display device for a record player according to the present invention includes a contact type switch provided on the surface of the transparent or semi-transparent part of the lid member, and a display element embedded within the thickness of the transparent or semi-transparent part. It is a feature.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a plan view showing an embodiment of the present invention, in which parts equivalent to those in FIG. 1 are designated by the same reference numerals.

In the figure, the dust cover 3 as a lid member is a transparent (or semi-transparent) part made of plastic etc. so that the moving state of the pickup 7 and the rotating state of the record disc 5 placed on the turntable can be visually observed from the outside. 3a
have.

On the surface of the transparent part 3a of the dust cover 3, there is a start/stop switch 6 and a pickup 4 for instructing to start playing (START) or stop playing (STOP).
an up switch 7a and a town switch 7b for commanding the rise and fall of the record, a repeat switch 8 for repeatedly playing, and 33 for setting the rotation speed of the record.
1/3 switch 9a and 45 switch 9b and up switch 10 for adjusting the rotation speed of the phono motor
A, a down switch 10b, etc. are provided to form the operating section.

Each of these switches has a tangential switch (so-called touch switch) configuration, and is composed of electrodes made of metal 11 deposited on the surface of the dust cover 3, as shown in FIG. 3a.

This vapor-deposited metal 11 constitutes the electrode of the switch and also serves as a wiring pattern.

Further, as shown in FIG. 3, it is also possible to configure a contact type switch using a conductive plastic 12 embedded in the dust cover 3 so that one end slightly protrudes from the surface of the dust cover 3. The vapor-deposited metal 11 provided on the back surface becomes a wiring pattern.

On the back side of the dust cover 3 at the locations where these switches are arranged, there are letters and the like indicating what kind of operation switch they are.

Further, the dust cover 3 has a rising display element 13 that indicates that the pickup 4 is in the rising and falling operating states.
A and descending display elements 13b, a repeat display element 14 indicating that repeat performance is designated, and a rotation number display element 15 indicating the number of rotations of the record disc, etc., are provided to constitute a display section.

The display elements 13a, 13b and 14 have a dot display configuration,
As shown in FIG. 4a, it is composed of, for example, a light emitting diode 16 embedded within the thickness of the dust cover 3.

Wiring to this light emitting diode is performed by a lead wire 17 buried within the thickness of the dust cover 3.

On the other hand, the rotational speed display element 15 has a digital display configuration including, for example, seven elements, and each element 18 is embedded within the thickness of the dust cover 3, as shown in FIG.

The wiring to each element is, for example, the dust cover 3.
This is done by vapor deposited metal 19 provided on the back surface of the .

Thus, according to the operation and display device according to the present invention,
Since there is no need to provide a special space, this is effective in reducing the size of the player, and since the player can be operated while visually observing the inside of the player, operability can be improved.

Furthermore, the appearance can be expected to be novel due to its placement on the dust cover.

Furthermore, such an operation and display device is most suitable for small players, thin players, wall-mounted players, and the like.
